The first two work in the foreground but won’t work while the app is in the background (the accelerometer readings are paused and are resumed while on the foreground again). The Generic Sensor API won’t work at all, even if I use this polyfill: https://github.com/kenchris/sensor-polyfills

How can an Ionic app use the accelerometer while in background? Any plugin that I am not aware of its existence (e.g., the Ionic Background Geolocation lets the app receive locations while in background)? Any other way?
